CEC database parameters

The module's own CEC parameters, for the CEC six-parameter model

What it is

The parameters of the module's entry in the California Energy Commission's module database: a_ref (V), I_L,ref (A), I_0,ref (A), R_s (Ω), R_sh,ref (Ω), Adjust (%), α_sc (A/K), β_oc (V/K), the cells in series, the rated NOCT (°C), the area (m²) and the entry's V_mp, I_mp, V_oc and I_sc at standard conditions. The CEC six-parameter module model with this module's parameters, and the NOCT model with the module's rated NOCT, read them.

Typical values and how to get it

Every module of the CEC library carries them; the CEC import keeps them from the CEC database. If not given: the CEC module model with this module's parameters is unavailable, and the NOCT model with the module's rated NOCT uses 45 °C.
